Breakthrough switching speed with an all-optical chalcogenide glass chip: 640 Gbit/s demultiplexing.

High Speed Networks SCALABLE 640-GBIT/S ATM SWITCHING SYSTEM WITH SELF-LOAD BALANCING MECHANISM

A T-bit/s ATM switching system architecture, called the OPTlMA switch, is proposed. This system is scalable and quasi-non-blocking by virtue of its self-load-balancing mechanism and high-speed interconnection effect. The selfload-balancing mechanism prevents overloading in the switch by automatically checking and balancing the internal load. An experimental 640-Gbitls ATM switching system was d...

Error-free all-optical add-drop multiplexing using HNLF in a NOLM at 160 Gbit/s - Electronics Letters

Introduction: An add-drop multiplexer (ADM) is one of the key elements in optical time division multiplexed (OTDM) networks. Various methods of performing OTDM add-drop have been demonstrated. Recently add-drop operation at 16 10 Gbit=s has been demonstrated with the use of a gain transparent ultrafast nonlinear interferometer (GT-UNI) [1] switch and at 4 40 Gbit=s with travelling-wave electroa...

Generation of a 640 Gbit/s NRZ OTDM signal using a silicon microring resonator.

A 640 Gbit/s NRZ OTDM signal has been successfully generated for the first time by format conversion of a 640 Gbit/s OTDM signal from RZ to NRZ. First, a coherent 640 Gbit/s OTDM RZ signal is generated by wavelength conversion of the original incoherent OTDM signal utilizing Kerr switching in a highly nonlinear fiber. Second, RZ-to-NRZ format conversion is achieved in a specially designed silic...
